Abstract

The utility model relates to camber type piano keys. Piano key surfaces of parts stick with ivory are made into trapezoidal camber surfaces to make finger playing on the keys more convenient and more rapid. Key pin holes are moved towards to the end of the keys to decrease keystroke depth, accelerate playing speed and playing frequency and enhance playing skills. Key top hammers are moved inwards to the end of the keys to increase the strength of the piano hammers striking on strings. Balancing weight blocks are glued under the end part of key bodies to increase playing strength of fingers.

Description

Camber type piano key

The utility model relates to the transformation of piano key shape and structure, also is applicable to other various keyboard instruments.

After Italian Ke Li David Stauffer profit in 1710 was modern piano with the clavichord transformation of the way, over more than 280 year, people never carried out big improvement on piano key.Present key surface is the plane, and (in vain) key need to be pressed the degree of depth when playing the musical instrument be that 10 millimeters (black key is 8 millimeters) qin Chui just can hit and ring string.Speed that these are played the musical instrument to people and skill (as: refer to, wheel refers to, plays tritone, scrape and play etc.) all have certain influence.Make people very difficult when playing highly difficult piano song.

The purpose of this utility model provides a kind of key surface and is trapezoidal curved surface, the piano key that the button degree of depth is more shallow, and the speed that it can not only make people play piano improves, and the skill that people are played the musical instrument improves.For playing more highly difficult piano song, the person of playing the musical instrument who is engaged in specialty and hobby provides advantageous conditions.

The utility model is achieved in that and will keeps the plane of former key wide 2/3rds in the middle of the white key of piano (the black key principle the is also identical) surface, both sides respectively account for the plane of the wide sixth of key and make to the inclined-plane of surface level with the 30 °-45 that has a down dip, inclined-plane and plane are smooth connection (not having intersection), when this plays finger on key, more convenient, rapider.The 40-45 millimeter is moved in the key pin hole outside the key afterbody, this makes the finger button degree of depth be kept to the 6-7 millimeter, has accelerated the frequency and the speed of finger keystroke.Key is pushed up Chui in the key afterbody, move the 5-10 millimeter, to increase the dynamics that qin Chui knocks string.Stickup balancing weight below the key afterbody (wooden or iron all can) increases finger and plays dynamics.

Owing to adopt such scheme, can make people's speeding up when playing piano; Simultaneously, original level of playing is significantly improved.

Shape of the present utility model, structure are by following examples explanation.

Fig. 1 is that the C(of the utility model central authorities is white) the embodiment side view of key.

Fig. 2 is the I-I cross-sectional view of Fig. 1.

Fig. 3 is that the C(of the utility model central authorities is white) vertical view of key.

Among the figure, 1, balancing weight; 2, ivory veneer; 3, key pin hole; 4, key body; 5, key top Chui; 6, the position in former key pin hole; 7, the position of former key top Chui.

In Fig. 1, key body (4) afterbody and ivory veneer (2) are pasted together, the 40-45 millimeter is moved than the position (6) in former key pin hole in the position in key pin hole (3) outside the key tail end, the 5-10 millimeter is moved than the position (7) of former key top Chui in the position of key top Chui (5) in the key tail end, balancing weight (1) sticks on the bottom of key body (4) tail end.

In Fig. 2, key body (4) afterbody is made trapezoidal curved surface on the surface that is stained with ivory veneer (2), two trapezoidal inclined-planes to horizontal line with the 30 °-45 that has a down dip, and with horizontal surface smooth connection (in vertical view, not having intersection).

In Fig. 3, key pin hole (3) are slot.

Claims

1, a kind of curved face type piano key, trapezoidal curved surface is made on the key surface of posting the ivory part, and the key pin hole is moved outside the key afterbody, and key top Chui moves in the key afterbody, stickup balancing weight below key body afterbody is characterized in that: the key upper surface is trapezoidal curve form.

2, curved face type piano key according to claim 1 is characterized in that: the 40-45 millimeter is moved in the key pin hole outside the key afterbody.

3, curved face type piano key according to claim 1 is characterized in that: key top Chui moves the 5-10 millimeter in the key afterbody.

4, curved face type piano key according to claim 1 is characterized in that: stickup balancing weight below key body afterbody (wooden or iron all can).
